Chris Coleman has expressed his surprise Aaron Ramsey was in the Arsenal team on the opening weekend of the season to suffer the injury which has ruled him out of Wales' World Cup opener.
Ramsey played in Arsenal's 4-3 Premier League defeat to Liverpool on August 14, having only been back in training a fortnight after helping Wales reach the semi-final of Euro 2016.
Mesut Ozil, Olivier Giroud and Laurent Koscielny were allowed extra time to recover after Euro 2016 and Arsenal manager Arsene Wenger's decision to play Ramsey backfired when the Wales midfielder suffered a hamstring injury to sideline him for a month.
